Hello. I just installed Ubuntu 8.10 Server Edition on my Dell R300. I did that from the Perfect Server description. Everything except the mail server works great. Thing is...i cannot ping mail.example.com (example.com beeing my domain) the output of the files is cat /etc/hosts 127.0.0.1 localhost 89.xxx.xxx.xxx server1 cat /etc/hostname server1 cat /etc/bind/named.conf options { pid-file "/var/run/bind/run/named.pid"; directory "/etc/bind"; auth-nxdomain no; /* * If there is a firewall between you and nameservers you want * to talk to, you might need to uncomment the query-source * directive below.

I have an external IP and i access on port 81 ispconfig. I want to host 4 domains, each with 1 subdomain for webmail. I need mail.example.com accessable. If i ping it i get this: ping mail.example.com ping: unknown host mail.example.com (once again, example.com is my example domain, it's not the real one ) What did i do wrong? Furthermore...i want to host 4 domains in the future...let's say example.com otherexample.com example3.com and example4.com Now...i wanna have a dns entry for each one of mail.example.com, mail.otherexample.com etc...how can i host mail server for 4 domains? let's say when i config the mail manager, i put at server mail.example.com, on another account mail.example3.com etc.. Basically i wanna host 4 mail servers for each of the 4 domains... Is it possible?
That is because you do not have an A record for mail.example.com, and you do not even have an MX record for your domain. you need these entries Code: @ IN MX 10 mail.example.com mail IN A _mail_server_ip_address
I made an A record for the mail and ns and now everything is working fine. thank you very much for your answer. Furthermore, can i use the same mail server for another 3 domains i will host?
There are various ways to do postfix virtual hosting am not sure which ones are compartable with howto u used. Details on setting up postfix virtual hosting can be found here http://www.postfix.org/VIRTUAL_README.html
